Hemp is harvested for its fibers for hemp clothing and seeds for hemp oil. With a relatively short growth cycle of 100-120 days, it is an efficient and economical crop for farmers to grow, however, industrial hemp cannot be commercially grown in the United States because it is erroneously confounded with marijuana. In fact, industrial hemp and marijuana are different breeds of Cannabis sativa. Smoking large amounts of hemp flowers can produce a headache but not a high!
Recycling is the reprocessing of old materials into new products, with the aims of preventing the waste of potentially useful materials, reducing the consumption of fresh raw materials, reducing energy usage, reducing air (from incineration) and water (from landfilling) pollution by reducing the need for "conventional" waste disposal, and lowering greenhouse gas emissions as compared to virgin production.
Reclaimed lumber is used wood that has been taken for re-use, often from long-standing idle buildings, and is sometimes refinished for new purposes. Most reclaimed lumber comes from timbers and decking rescued from old barns, factories and warehouses and some companies have been known to source wood from less traditional structures such as boxcars, coal mines, and wine barrels.
